Yesterday my throat went really saw after drinking a very sour fruit juice. I then began to feel weak and didn t know where to put myself , my throat got worse and it really ached. I went to bed, and woke up today with a bad cold, all my muscles aching especially in my legs, feeling weak, don t know where to put myself, headache at times, and at the edge of my right cheek where there s a bone which joins onto the ear, above the jaw line, it aches a little when I touch it. I have no previous medical history and have been healthy and well for months, what could this be? And is it connected to the fruit juice? How can I get better and feel well again?
